Working Principles

The GD25WD20CEIGR is based on NAND flash memory technology. It stores data in a series of memory cells organized in a grid-like structure. Each cell can store multiple bits of information, allowing for high-density storage. The memory cells are programmed and erased using electrical charges, which alter the state of the floating gate within each cell. This allows for non-volatile data storage that remains intact even when power is removed.
